The objective of this study was to determine the optimal dietary concentration of zinc and manganese on the performance characteristic and the requirement of these trace minerals derived from organic sources for broilers from 1 to 42 days of age. In experiment 1, zinc was evaluated, whereas manganese was evaluated in experiment 2. In each experiment, 320 males chicks were distributed in iron mesh metabolic cages (0.9m x 0.7m x 0.5m), according to a completely randomized experimental design in eight treatments with five replicates of eight birds each. In experiment 1, zinc sulfate was included at 0,60 and 100mg/kg and zinc methionine at 20, 40, 60, 80 and 100mg/kg. In experiment 2, manganese sulfate was added at 0, 65 and 105mg/kg and manganese methionine at 25, 45, 65, 85 and 105 mg/kg. Trace mineral requirements were determined comparing only organic trace mineral levels. The evaluated trace minerals (zinc and manganese) did not influence broiler performance, independently of source or level. It was concluded that the requirements of broilers from 1 to 42 days of age were supplied with no addition of zinc or manganese, under the conditions of the present experiments. However, under commercial rearing conditions, which are more challenging, the use of levels higher than 33.00 mg/kg and37.80 mg/kg of zinc and manganese, respectively, may be justified.

“…Supplementation of Zn and vitamin E in combination did not affect the phosphorus and zinc contents of the tibia, although, a recent study showed that dietary supplementation of zinc significantly affected phosphorus contents of the tibia (Sunder et al, 2008;Vieira et al, 2013). Supplementation of zinc at a dose of 40 ppm produced optimum levels of phosphorus by 17.59%.…”

The purpose of this study was to determine the effect of zinc (Zn) and vitamin E supplementations on apparent nutrient digestibility, carcass traits, and mineral availability of broiler in tropical environment. The experiment was arranged in a 3 x 3 factorial design with 4 replications in each treatment (10 birds each). The dietary treatments were the combination of doses of zinc (A1: 0 ppm, A2: 40 ppm, A3: 80 ppm) and vitamin E (B1: 0 ppm, B2: 125 ppm, B3: 250 ppm) supplementations. The variables observed were apparent nutrient digestibilities (apparent crude protein digestibility and apparent ether extract digestibility), carcass traits (final weight, the percentage of carcass weight, breast weight, thigh weight, wings weight, and back weight), meat bone ratio and mineral availability in the tibia (calcium [Ca], phosphorus [P], and zinc [Zn]). The results showed that apparent nutrient digestibility, carcass traits (the percentages of carcass, breast, thighs, wings, and back), meat bone ratio were not significantly influenced by the supplementation of zinc or vitamin E. The supplementation of 80 ppm of Zn and 0 ppm of vitamin E significantly (P<0.05) increased final weight of broiler. Supplementation of zinc alone and vitamin E alone in the diet significantly (P<0.05) increased calcium content of the tibia. In conclusion, supplementation of 80 ppm of Zn increased calcium content compared to control, but did not affect final weight and ether-extract digestibility. Supplementation of vitamin E at a dose of 125 ppm could increase calcium content of the tibia compared to control.

“…Follicular inductive sites in the intestine are rich in cytokines with IgA-inducing functions, including transforming growth factor β (TGF-β) and interleukin 17 (IL-17) (Cerutti & Rescigno, 2008). On the other hand, zinc is known to modulate some immunological parameters in vitro (Zhao, Li, Chen, Hu, & Zhao, 2016) and in broilers has a positive effect on the immunological capacity by improving the levels of immunoglobulins IgA, IgM, and IgG (Vieira et al, 2013). Zinc supplementation decreases oxidative stress markers and increases phagocytosis, Moreover, Zn promotes monocyte adhesion to endothelial cells in vitro and is important for the production of pro-inflammatory cytokines (Bonaventura, Benedetti, Albarède, & Miossec, 2015).…”

The study compared the effect of dietary supplementation with an inorganic or organic source of zinc (Zn) on mucin 2 (MUC-2) and IgA gene expression, the cytokines IL-17 and TGF-β4 and the secretory IgA content (sIgA) in broiler jejunum. One-day-old chickens were fed an unsupplemented basal diet (BD) or the same BD supplemented with 30 or 70 mg/kg of added Zn from ZnSO 4 ·H 2 O or Zn chelate of glycine hydrate for 40 days. The highly expressed MUC-2 and IgA genes were observed in both groups supplemented with the low-dose Zn sources (30 mg/kg). A higher sIgA concentration was observed in both the ZnSO 4 groups and the glycine-zinc/30 mg group. Our data indicate that the organic Zn chelate has better availability than the inorganic Zn source, and the low-dose Zn diets proved to be more beneficial to the maintenance of intestinal immune homeostasis.
